VTP domain and transparent mode

I have got scenario with this requirements:

Configure the VTP domain ANYANY between SW11 and SW22.

Create and configure the VLAN assignments on SW11 and SW22 as follow:

----

------

------

In his configuration he used :

SW11:

vtp domain ANYANY

vtp mode transparent

vtp password cisco

!

vlan 5,28,40,164

SW22:

vtp domain CCIE-------------By default it is server mode

vtp password CISCO

!

vlan 3,9,56,89,189

Yes I knew that in VTP there are three modes of operation. These modes are :

1- Server.

2- Client.

3- Transparent.

A bridge in server mode can add, remove, or change parameters of the VTP domain.

VTP clients listen for updates from servers,install parameters advertised, and pass these advertisements on.

A bridge running in VTP transparent mode, as the name implies, passes VTP updates on transparently without installing them.

A bridge running in transparent mode effectively does not participate in VTP with the rest of the domain, and keeps a

separate local copy of the vtp database.

Why did he use transparent mode ? Is there any implicit indication for that ?

Re: VTP domain and transparent mode

Hi Zillah,

In many big networks people generally do not configure VTP server and client mode because many a times it is required to create vlans at different switches locally which network admin or design guys do not want to propogate in into the network.

Many a times it is required to add a vlan in a switch which is already having another vlans but you do not want that vlan to be anywhere else in your network it is preferred to have switch in tranpsratent mode because transparenet mode allows you to create, delete and modify vlan database on your switch and will not propogate it anywhere in the network.

HTH , if yes please rate the post.

Re: VTP domain and transparent mode

((because transparenet mode allows you to create, delete and modify vlan database on your switch and will not propogate it anywhere in the network))

Does that mean the similarity and difference between transparent mode and server mode,,,that in both of them we can create, modify, delete VALNs,,,,,,but in transparenent a switch does not propogate valns while in server it does ?

Re: VTP domain and transparent mode

Hi Zillah,

Yes you are right. In server and transparent mode you are allowed to create, delete and modify vlan database but in tranpsarent mode it is not propagated to the newtork but in server mode it is.

HTH, if yes please rate the post.

Re: VTP domain and transparent mode

Recall: ((A bridge running in VTP transparent mode, as the name implies, passes VTP updates on transparently without installing them)) and ((delete and modify vlan database but in tranpsarent mode it is not propagated to the newtork ))

How can you manage to understand the two quoted above ?

What does it mean by his phrase :"the name implies, passes VTP updates on" ? could you explain

Re: VTP domain and transparent mode

Hi Zillah,

The phrase implies that if there is a switch in transparent mode in between switch running VTP server and client mode and any update coming from VTP server switch will be passed by the VTP transparent switch to the client switch and will not be updated on the VTP transpareent switch.

VTP server ---- transparent ---client

Now if any vlan is updated in vtp transparent switch it will not at all will leave the transparent switch and remain local to the switch.

HTH, please rate all post.
